Disclosed herein is an image encoding/decoding method and apparatus. The image decoding method includes deriving an intra prediction value by performing intra prediction with respect to a current block, deriving an inter prediction value by performing inter prediction with respect to the current block, deriving a combined inter intra prediction (CIIP) value by weighting the intra prediction value and the inter prediction value, and generating a reconstructed block of the current block using the CIIP value. The intra prediction is performed in a Planar mode.
Legal claims defining the scope of protection, as filed with the USPTO.
3. The image decoding method of claim 1, wherein, when at least one of a width or height of the current block is less than 8, the CIIP mode information is not acquired from the bitstream.
4. The image decoding method of claim 1, wherein, when at least one of a width or height of the current block is greater than or equal to 128, the GIP mode information is not acquired from the bitstream.
7. The image encoding method of claim 5, wherein, when at least one of a width or height of the current block is less than 8, the CIIP mode information is not encoded.
8. The image encoding method of claim 5, wherein, when at least one of a width or height of the current block is greater than or equal to 128, the CIIP mode information is not encoded.
